The Philadelphia crane operator, who was wanted in connection with a building collapse that killed six people last week, has turned himself in to police, according to The Inquirer.

Sean Benschop, 43, who surrendered on Saturday, refused to give a statement on his role in Wednesday's collapse, according to The Inquirer. He is scheduled to be arraigned, but a time has not been set.

He was charged with six counts of involuntary manslaughter, 13 counts of recklessly endangering another person, and one count of risking a catastrophe, police said.

At the time of the collapse, he was working for Griffin T. Campbell, the contractor hired by property owner Richard C. Basciano to tear down a four-story building next to the thrift store. On Wednesday, the remaining portion of that building collapsed during demolition and fell onto the store. There were 20 people inside.

Salvation Army employees Kimberly Finnegan and Borbor Davis and shoppers Juanita Harmon, Mary Simpson, Anne Bryan, and Roseline Conteh were killed. Fourteen others were injured. One survivor, Myra Plekan, spent more than 12 hours in the rubble before she was rescued by firefighters.

Sunday at noon, experts retained by the law firm Saltz Mongeluzzi Barrett & Bendesky will be inspecting the site for evidence. The firm filed suit against the owner and contractor on behalf of Nadine White, a Salvation Army store clerk who survived.
